Part 12: 13B Rotary Engine Rebuild - My 76 Mazda RX-5 Cosmo Restoration
Just as I promised last episode, it is finally time to build the engine!
Part 12 of my RX-5 Cosmo restoration covers the entire process of building
the 6 port 13B Mazda rotary engine. While this engine is a hybrid of GSL-SE
RX-7 and Cosmo parts, the process is the same for any rotary from a 12A to
a 13B NA, 13B turbo, 13B-REW or any
other variant of the 13B. This video shows the whole process of the engine
build, starting from measuring the rotors and covering everything else
including clearancing the side seals, assembling the rotors, complete
assembly the short block, setting the eccentric shaft end play and
installing the front cover and everything underneath it. It's probably the
most complete engine build video outside of what you can buy from the
vendors, and as such, is an hour long. After this one, I'm going back to
videos under 20 minutes. But for now, grab a beverage of your choice, sit
back, and enjoy.

been taken very good care of over the years. The exterior is as nice as it
gets. The paint looks great and has a very nice shine to it. All of the
trim looks great and clean. Has the very nice polished aluminum wheels that
really give the car a sporty look. It has the dual tops with a hard top and
a sun roof. The interior is very clean and shows very little wear. It is
fully loaded with all the options, leather, power everything, factoy a/c,

car. Thank You for watching and please Share my Videos Comment on the Like

The Series 3 (1984--1985) featured an updated lower front fascia. North
American models received a different instrument cluster (the NA S3 RX-7 is
the only rotary-engined car to not have a centrally mounted tachometer).
GSL package was continued into this series, but Mazda introduced the GSL-SE
sub-model. The GSL-SE had a fuel-injected 1.3 L 13B RE-EGI engine producing
135 hp (101 kW) and 135 lb·ft (183 N·m). GSL-SEs had much the same
options as the GSL (clutch-type rear LSD and rear disc brakes), but the
brake rotors were larger, allowing Mazda to use the more common lug nuts
(versus bolts), and a new bolt pattern of 4x114.3 (4x4.5"). Also, they had
upgraded suspension with stiffer springs and shocks. The external oil
cooler was reintroduced, after being dropped in the 1983 model-year for the
controversial "beehive" water-oil heat exchanger.
The 1984 RX-7 GSL has an estimated 29 highway miles per gallon (8.11 litres
per 100 km) /19 estimated city miles per gallon (12.37 l/100 km). According
to Mazda, its rotary engine, licensed by NSU-Wankel allowed the RX-7 GSL to
accelerate from 0 to 50 (80 km/h) in 6.3 seconds. Kelley Blue Book, in its
January--February 1984 issue, noted that a 1981 RX-7 GSL retained 93.4% of
its original sticker price.
